CABLE-LIFTER FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No.402,544, dated April 30, 1889. Application fllefl September 15, 1888. ReneWedApril 4,1889. Serial No. 306,028. (No model.)

To all whom it may concern,.-

Beit known that I, DANIEL W. SMITH, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Cable-Lifters for Railway-Cars,

`of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in whichp v Figure I is a detail vertical longitudinal section through a conduit and a transverse section of a crossing-conduit of a cable railway. This section is taken on line I I, Fig. III. Figs. II and III are longitudinal horizontal sections taken on line II III, Fig. I,the two figures showingV the beam and other parts in dierent positions. Fig. IV is an enlarged top Vview of the beam. Fig. V is a section taken on line V V, Fig. IV. Fig. VI is a transverse section taken on line VI VI, Fig. II. Fig. VII is a transverse section taken on line VII VII, Fig. II.

My invention relates to an improved device for lifting the cable of a street-railway to per- Init it to be taken up or grasped by the grip after crossing another track.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, l represents the conduit of a cable road, and 2 the cable of this conduit.

3 represents the conduit on another road, which crosses the conduit l, and 4 represents its cable. The cable 2 passes beneath the cable 4, running under pulleys 5, as usual.

The grips of the cars of conduit l have, of course, to'drop the cable in crossing the conduit 3; and my invention relates to a device for lifting the cable so that the grips may take it up again after crossing the conduit 3.

The invention consists in a beam, 6, pivoted in the center, as shown at 7, to a suitable bracket or support, 8, (see Fig. V,) the bracket or support being made fast to the bottom of the conduit or to some other suitaable fixed object. The beam is thus allowed to rock horizontally on its pivot from they p0- sition shown in Fig. II to the position shown in Fig. III, and vice versa. On each end of the beam a roller, 9, is mounted, each roller threaded or screw periphery, as shown in Figs. I and VII. They may, however, 'have smooth peripheries, if desired, as shown in Fig. V. These rollers stand vertically, and are preferably secured to the beam by Ineans of pivot pins or bolts l() and U `haped plates ll, the plates and bolts forming clevises. At the upper end of each roller is preferably a grooved pulley, l2. Each end of the beam is connected by a link, 13, and bolt 14 to a segment or arm l5, secured to a rock-shaft, 16, mounted in suitable boxes, 17, by which it is secured to one side of the conduit, the shafts on the respective ends of the beam being secured, preferably, to the opposite sides of the conduit. On each shaft 16 is a lever 18. The bolts 14 preferably fit in slots 19 of the segments or arms l5 to permit of an adjustment to regulate the throw of the beam. (See righthand sideof' Fig. III.)

being preferably of cone shape and having a The cable passes on one side of one of the rollers and on the opposite side of the other roller, and when it is in its normal position and the beam is in its normal position the cable crosses the center or pivot of the beam, as shown in Fig. II.

The operation is as follows: Supposing a ear to be moving in the directiony indicated by the arrows in Figs. I, II, and III, the grip 2O would be above the cable as the latter is depressed by passing under the pulleys 5. As the car advances, the grip comes against the lever 18 at the near end ofthe beam, and turning it rocks the shaft 16 and through means of the described connection rocks the beam 6 from the position shown in Fig. II to the position shown in Fig. III. This causes the cable to be engaged by both of the rollers 9, one roller bearing on one side of the cable and the'other on the other side. The movement of the cable causes the rollers to revolve, and this turning of the rollers elevates the cable by frietional contact with the rollers unt-il it enters the grooved pulleys l2 at the upper ends of the rollers. The car is all this time moving forward, and by the time the grip has grip, and as the car continues to advance the grip strikes the lever 1S at the far end of the l beam and rocks the shaft 16 at this end of the beam, thus moving the beam back to the position shown in Fig. II, permitting the grip to pass the roller at this end of the beam Without striking it. In this manner I produce an automatic lift for the cable.

The invention is doubtless susceptible of various changes or modifications in the manner of constructing or arranging the parts, and I do not confine myself to these matters of detail.

The pulleys 12 might possibly be dispensed with Without materially affecting the operation of the device.

My preferred manner of making the beam consists in bending a channel-bar into the shape shown in Figs. II, III, and IV, and connecting the opposite sides by crossing-strips 21,Which would be riveted to each other and to the channel-bar.

I claim as my inventionl. In a cable-lifter, the combination of a pivoted beam, rollers on the beam for elevating the cable, and mechanism for operating the beam automaticallythrough means of the grip, substantially as set forth.

2. In a cable-lifter, the combination of a plvoted beam, rollers secured to the opposite ends of the beam, a cable passing on opposite sides of said rollers, and mechanism for moving the beam automatically through means of the grip, substantially as set forth.

3. In a cable-lifter, the combination of the pivoted beam, conical rollers secured to the opposite ends of the beam, a cable passing on the opposite sides of said rollers, and mechanism for moving the beam automatically through means of the grip, substantially as set forth.

4. In a cable-lifter, the combination of the pivoted beam, rollers. mounted on opposite ends of the beam and having threaded peripheries, a cable passing on opposite sides of the rollers, and mechanism for moving the beam automatically through means of the grip, substantially as set forth.

5. In a cable-lifter, the combination of the pivoted beam, rollers mounted on opposite ends of the beam, grooved pulleys on top of the rollers, a cable passing on opposite sides of the rollers, and mechanism for moving the beam automatically through means of the grip, substantially as set forth.

G. In a cable-lifter, the combination of the pivoted beam, rollers mounted on opposite ends of the beam, clevises securing the rollers to the beam, a cable passing on opposite sides of the rollers, and mechanism for moving the beam automatically through means of the grip, substantially as set forth.

7. In a cable-lifter, the combination of the pivoted beam, rollers mounted on opposite ends of the beam, and mechanism for moving the beam automatically through means of the grip, said mechanism consisting of rock-shafts, levers secured to the rock-shafts, segments or arms secured to the rock-shafts, and links connecting the segments or arms to the respective ends of the beam, substantially as and for the purpose set forth.

S. In a cable-lifter, the combination of the pivoted beam, rollers secured to the opposite ends of the beam, mechanism for moving the beam automatically through means of the grip, said mechanism consisting of rock-shafts, levers secured to the rock-shafts, arms or segments secured to the rock-shafts, and links connecting the arms or segments with the beam, said links having slot-and-pin connection with said segments, substantially as set forth.

9. In a cablelifter, the combination of the beam, rollers, and mechanism for moving the beam, said beam consisting of channel-bars connected by crossing-strips, substantially as set forth.
